ABSTRACT:
A composite annular seal for a rotary ball valve or ball joint comprises a sealing ring (C) of low friction material intended to engage the ball (2), a first metal ring (A) of which part of one face is adapted resiliently to engage and conform with part of the surface of the sealing ring (C) while a radially more inward part of the face is adapted to engage and conform with the curvature of the ball (2), a second metal ring (B) which supports the first metal ring (A), having a radially outer part which overlaps the radially outer part of the sealing ring (C) and the radially outer part of the first metal ring (A) and of which a part is adapted to be in area contact with a part of the first metal ring (A), and a layer (D) of soft non-metallic material bonded to the axially outward surface of the second metal ring (B) for separating that part of the second metal ring (B) from the part of the housing (1) into which the seal is intended to be installed.
